Are men who are sociopathic and absolutely hate women more likely to sexually abuse them?

Well, it's certainly not impossible that he harmed you. And definitely that kind of mindset is going to incline someone toward all sorts of violent acts. The question is whether it was these specific acts, and whether they were directed toward you.

I realize that you are only sixteen, but it would help to speak with a therapist. I know that getting to that point is not easy when you are a minor, but I am sure that your parents are well aware of your brother's issues. You could frame it in terms of seeking help in coping with having such a brother. If that is too much, then ask to see your regular pediatrician. Complain of headaches if you must (I hate the idea of lying in this area, but I understand that you may be in a position where providing the whole truth to your folks will do more harm than good) and ask the doctor for a referral to a mental health specialist. At least to talk should help.

Best of luck to you.

Not sure . And not sure about your terms but tbh, So many females act terrible 😒😒😒 . Seems somewhat cos they never called out hardly. Male anger is possibly partly a reaction to the obcene selfishness and absurd victim status and virtue signaling and the harlotry rammed down their throat on a daily basis. So although no one is perfect , im not sure weather ''sociopth' is accurate anyway. Have you tried extending maybe more empathy?
Take care anyway
